gateway_resource_policy_delete
AI agents call gateway_resource_policy_delete to permanently remove resources in AWS IoT SiteWise MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool explicitly performs deletion ('delete' in name) on a gateway resource policy, which is a critical access control mechanism. Deletion of resource policies is irreversible and could disable gateway authentication/authorization, causing service disruption. This fits the Destructive category (irreversibly deletes or overwrites data) rather than Write because policy deletion cannot be trivially undone.
From the tool's definition Tool name contains 'delete' and operates on 'gateway_resource_policy', indicating irreversible removal of access control policies from AWS IoT SiteWise gateways.
Attacks that exploit this kind of access
gateway_resource_policy_delete. It is categorised as a Destructive tool in the AWS IoT SiteWise MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for gateway_resource_policy_delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AWS IoT SiteWise MCP Server. Nothing to install.
gateway_resource_policy_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the gateway_resource_policy_delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gateway_resource_policy_delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gateway_resource_policy_delete is provided by the AWS IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
